What kind of spanning tree is configured on that other switch?
If only I knew ;-)
BTW I think it is quite strange that you have a "private network"
comprising at least one switch connected to your LAN. If this means that
some other LAN outside your control is connected to your own LAN, you
have a recipe for trouble...
It's a custom setup by a vendor and we only have partial control over that...
Does this setup need a layer 2 connection? Otherwise you could configure
a "routed port" (one separate VLAN just for this port, no spanning tree,
no tagged frames) to connect that custom setup.
For now I have tried to prepare myself for the upcoming sniffing session
tomorrow and now I am wondering about the PortID in the BPDU frame. If I receive
a value of e.g. 0x8085, then the port ID would be 133 (0x85 = decimal 133). What
index is that?
Sorry, I don't know and don't want to speculate.
But you might take a look at NetSight (or use your preferred SNMP tools)
to check on interface indexes and names of your switches.
Br,
Erik
